Frequently Asked Questions
How do I blur part of an image?
Upload your image, use the radius slider to set blur intensity (1–50px), and click Blur. For selective blur, crop the area first, then apply blur.
What blur radius should I use?
A radius of 1–5px gives a subtle softening effect. 10–20px creates noticeable blur suitable for hiding details. 30–50px produces heavy blur that fully obscures content.
Can I blur a photo to hide a face or license plate?
Yes. Use the crop tool first to isolate the area you want blurred, then apply the blur effect. This is commonly used for privacy before sharing photos publicly.
What format is the blurred image saved as?
The blurred image is saved as a PNG file, which preserves the full quality of the blurred result without additional compression artifacts.
